BUCKET FOR WATER-WH EELS.

SPECIFIGA TIGN forming part of Letters Patent N0. 651,101, dated June 5, 1900.

Application filed July 6,1899- Serial No. 723,005. No model.)

'1'0 (066 w/tom it may concern.-

Be it known that I, FRANK R. BROWN, a citizen of the United States, residing at Unga, Territory-of Alaska, have invented certain new and useful Improvements in Buckets for Water-Wheels, of which the following is a specification.

This invention relates to water-wheels, and particularly to that class known as hurdygurdy wheels, which are impelled by a stream or streams of water directed against buckets affixed to the periphery of the wheel; and it has for its object to provide such wheel with buckets of improved construction, by means of which increased efficiency is attained and the full effective impact force of the stream of water is obtained and by means of which the reactionary force of the water is utilized to aid in impelling the wheel instead of retarding it.

To this end my invention consists in the features and in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claim following the description, reference being had to the accompanying drawings, forming a part of this specification, wherein- Figure 1 is a perspective view of one of the buckets. Fig. 2 is a top plan view thereof.

Fig. 3 is a sectional view on the line :0 0c of Fig. 2. Fig. 4 is a similar view on the line y y of Fig. 2; and Fig. 5 is a view in elevation of a portion of the wheel, one of the buckets being shown in section, illustrating the mode of operation.

Referring to the drawings, the referenceletter A indicates the wheel, which may be of any approved or preferred construction, and B the nozzle, arranged tangentially to the wheel for discharging a stream of water fairly against the bottom of each of the buckets in succession.

The numeral 1 indicates one of the buckets, comprising a cup-shaped integral metallic casting having a perfectly-flat bottom 2 and upwardly and outwardly flaring sides 3, which are parallel with each other throughout their lengths. The sides 3 terminate at'their innor ends in two outwardly-curved or bulging portions 4:, which are inclined away from the iiat bottom 2 and separated centrally by an inwardly-projecting rib 4, while the opposite ends of the sides 3 terminate in two similarlyshaped bulging or curved portions 6, separated by a central rib 7. The outer face of the inner end of each bucket is very slightly curved and inclined relatively to the flat'bottom 2 of the bucket, whereby whensaid face or wall is seated against the periphery of the wheel the fiat bottom will lie at an angle to a radial line passed through the center of the wheel and the point of attachment thereto of the bucket, and on the inner end of the bucket are cast two integral projecting lugs 5, perforated as at 5, which straddle or embrace the opposite sides of the periphery of the wheel and are bolted thereto by abolt passed through said perforations and through the wheel. In Fig. 5 Ihave shown two bolts apassed through the ears of each bucket; but in practice one bolt will be sufficient, owing to the inclined face 4 having a firm seat or hearing throughout its length on the periphery of the wheel.

As shown in Fig. 5, the wateris discharged tangentially relatively to the wheel and successivel y strikes squarely and ata right angle against the perfectly flat bottom of each bucket, whereby the latter receives the full effective impact of the undivided stream. After the stream has thus been squarely directed against the flat bottom it is divided by the ribs 4 and 7 and flows out of the curved ends 4 and6 of the bucket and laterally along the outwardly-flaring sides 3, the water being freely discharged or deflected from the bucket upon all the walls of the latter, the reactionary force of the same, owing to the peculiar configuration described, operating to aid in impelling instead of retarding the bucket.

I am aware that water-wheel buckets having bulging or curved outer ends and a midfeather or rib extending longitudinally along the bottom have been used; but in such buckets the stream at the moment of impact with the bucket is divided, and, moreover, such buckets having fiat inner ends do not throw out the water with equal freedom at effective force of the stream is wholly utilized, and owing to the peculiar flaring shape of the ends and sides and the angle at which the buckets are set the reactionary force of the Water is utilized to the best advantage.

Having described my invention, what I claim is-- A bucket for Water-wheels comprising a cup-shaped casting having a perfectly-flat bottom and outwardly-flaring divergent sides, the inner and outer ends of said bucket each having two outwardly-flaring curved or bulgin g portions separated by an inwardly-projecting rib curved in cross-section and gradually merging at its lower end into the flat bottom of the bucket, substantialiy as described.

In testimony whereof I affix my signature in presence of two Witnesses.
